Visible crew/equipment: When the samurai are giving battle advice to the peasants, who sit around them forming a circle, the camera does a rather wide circle shot of them. You can see the camera track for the shot in most of scene behind the sitting peasants.

Visible crew/equipment: During the climactic battle scene in the rain a man is running and takes an arrow in the back. As he falls into the mud you can spot the wire that the arrow travelled along and which is attached to his back.

Toshiro Mifune's character, Kikuchiyo, travels to the bandits' camp and steals one of their two remaining fuselock muskets. Shortly afterward, the bandits fire twice at the samurai within five seconds with their last firearm. A fuselock takes as much as two minutes to reload, prime, and fire.

In some instances in the film, such as when Gorobei kills the bandit who was checking the water level with an arrow, the actors were actually shot with real arrows. The actor would simply wear a block of wood under his costume (which you can see if you know what to look for) and an expert archer would actually shoot him.
